Drawing Graphs

What does everyone use on linux to draw graphs?

I've used excel up to now, but am looking for something to make some nice graphs for my thesis on ubuntu.

thanks!

You should give gnumeric a try. The spreadsheet interface is a clone of Excel, so you should feel right at home. The graphing takes a little getting used to, but once you figure it out it is much more configurable than Excel.

The graphing capabilities in gnumeric are way better than excel.
Gnumeric's advantage is that it is not a clone of excel (like ooffice calc) but is different in many ways, often for the better. The interface for making graphs is different, but is more advanced. You can create multiple plots in a chart,etc. And you can save the chart as either .svg or as .png (you choose the resolution). I also sometimes use RLplot.

If you are comfortable using the command line interface, check out gnuplot.

I recently switched from R to gnuplot for graphing, and I'm astonished at how easily gnuplot can produce publication quality figures. Keep in mind that gnuplot is very CLI oriented when you make your decision.

Excellent, thanks for the help guys! I'll try those out now.
There is labplot in te repositories too

..and pylab/matplotlib for a more matlab type approach.

I think matplotlib makes the nicest looking graphs of all software I have used...

To my mind, the best and easiest to use open-source plotting package is RLPlot.

There's a feature in Exel - when you point your mousse over the graph, you can view the x and the y values. In wich application I can find this feature?
